A CRPORAJJIONY OIF NEW JERSEY FASTENING-INSERTING' MACHINE Application filed June 29,

This invention relates to fastening inserting machines and is illustrated as embodied in a machine particularly adapted to insert paper pegs in the manufacture of boots and shoes. y

The fasteningtogether of shoe parts by means of paper pegs, as disclosed and claimed in United States Letters Patent No. 1,729,169, granted on September 24, 1929, to Fred N. La Chapelle, has proved to be so successful that it has become desirable to develop fastening inserting machines particularly adapted to the insertion of pegs of this'character and therefore more satisfactory for such work than were most of the previously existing fastening inserting machines which were designed to insert metallic fastenings. It is, accordingly, an object of the present invention to provi le a simple, edective, and reliable fastening inserting machine of a. character well adapted to be used for the insertion of paper pegs in the manufacture of boots and shoes.

llf'hile tie nir-.chi e herein disclosed as emhodying the present invention is by no means limited in itsutility to the insertion of paper pegs of the character disclosed in said Patent No. l,T29,l69, it has been developed with a view particularly to the insertion of such pegs, and more specifically to the performance of such operations as, for example, McKay sole laying (that is the preliminary attachment of the soles of McKay .shoes by fastenings driven through the soles into the lasted uppers and irl-soles), in which mechanical means for feeding the work to and past the fastening inserting instrumentalities of the machine are not necessary and are not ordinarily used.

Then inserting pegs of the character referred to, it has so far been found necessary to make in the work piece a hole of substantially the full depth to which each fastening is to be driven. ln McKay sole laying, for example, such holes will extend from thesurface of the channel in the tread surface of the forepart and shank of the outsole and from the heel-seat portion of the outsole substantially through the insole of the shoe. As this distance is `greater in the heel-seat por- 1927. Serial No. 202,416.

tion of the shoe where there is no channel than in the forepart of the shoe, it is desirable to provide simple, and readily controlled means for varying the depths of the holes formed and for presenting for insertionv in the holes fastenings varying in length in accordance with the depths of the respective holes in which they are to be inserted. The` illustrated machine, therefore, in accordance with a feature of the invention, 1s provided with mean-s for varying thedepths of the holes formed in the Work, and for lcorrespondand the fastenings inserted are of a corresponding length, while when the treadle is displaced the awl -stroke of the tool extends deeper into the work and the fastenings supplied are correspondingly longer, the depth of the holes and the lengt-h of the fastenings, again preferably being capable of adjust-` ment. Stated another way, the treadle is movable between two positions, illustrated as mechanically determined by a pair of adjustable stops, and connections are 'provided between the treadle and the lhole forming and fastening supplyinginstrumentalities Lof the machine whereby When the treadle is -in one of said positions holes of one predetermined depth are formed and When the treadle is in the other of sL id positions holes of a (liderent predetermined depth are formed, the fastenings being suppliedineither case yof lengths corresponding to the' depths-of the holes in which they are to be inserted.

In order to simplify the constructionand to keep down the number of parts of the illustrated machine, a single tool'is utilized both as an awl and as a driver. e. Thistool is given two strokes in each cycle of operationof nthe machine, first an awl stroke in which it penetrates the work and forms a fastening receiving hole and second a. driver stroke in which it inserts a fastening in the hole which it has previously formed in the work. In accordance with a further feature of the invention, this tool is reciprocated by a rocking lever the fulcrum of which is moved according as the tool is to operate as an awl or as a driver. In accordance with anotherV feature of the invention other means are provided for positioning the fulcrum of this lever at the time of the awl stroke of the tool according to the desired depth of the hole to be formed in the work piece. As illustrated, these functions are performed by suitable link and lever mechanisms, the means for varying the stroke according as the tool is to act as an awl or as a driver being shown as cam operated and the means for varying the depth of the awl stroke being manually controlled.

Another feature of the invention comprises an improved feed mechanism for feeding the strip of fastening material from which the paper pegs are severed, toward severing position. As illustrated, this comprises a novel arrangement including a feed dog mounted upon a link and arranged for reciprocating movement to feed the strip of fastening mate- .rial,` another dog for retaining thestrip against retrograde movement between feed movements, and means for disengaging the feed dog from the strip of fastening material when the machine comes to rest so that the strip of material cannot be fed forward during the adjusting of the machine or in any manner unaccompanied bythe rotation of the main shaft of the machine.

A further feature of the invention comprises novel cont-rolling mechanism arranged to Cause the machine to come to rest at the end of a single cycle of operation in such condition that it can be lstarted again with little effort on the part of the operator. The illustrated machine is provided with a nozzle trip, the nozzle being connected to the clutch of the machine by mechanism operated, when the nozzle is displaced by upward pressure of the work piece against the nozzle, to start the machine. The novel controlling mechanism includes a toggle arranged when substantially broken to permit the clutch to become operative to drive the machine, the toggle being arranged to be held by a latch in a partly broken position while the machine is at rest. This lat-ch is connected to the nozzle of the machine so that a comparatively light pressure of the work piece against the nozzle trips the latch permitting the toggle to break sulficiently to permit the clutch to be thrown into driving position.

With the above and other objects/and features yin view, the invention will nowbe described in connection with the illustrated mafchine and pointed out in the accompanying claims. Itshouldbenoted,however,that While the illustrated machine comprises the best embodiment of the invention now known, the invention is clearly, in many of its aspects, capable of embodiment in other forms. 1t should accordingly ,be understood that the invention is not limited to the particular type of machine herein illustrated.

Fig. 10 is a horizontal section of the head f the machine on the line X-X of Fig. 4.

As shown particularly in Fig. 1 the machine is provided with a column 12 made up of two telescoping and relatively adjustable sections in the base 13 of which is housed a Vmotor 14 to which electricity is carried by a conductor housedin a conduit 16 and controlled by a switch contained in a box 18 and operated by a lever 20 projecting from the box 18. The rotor shaft 22 of the motor is coupled to a shaft 24 housed in the column 12 fast upon which is a bevel gear 25 meshing with a bevel gear 28 fast upon a shaft 30 adjustably connected to a shaft 32 arranged vertically in the column 12 of the machine and carrying at its upper end a bevel gear S4 4).

A heacL 36 is iiXed upon the top of the column 12 and is provided with a pair of large doors 38 (best shown in Figs. 8, 9, and 10) iliustrated as hinged at 40 (Fig. 1) and normall-y retained closed` by a latch as shown at 42 (Fig. S) but arranged to be opened to give access to the parts housed within.

vSuitably journaled in the` head of the mathus becomes eiectiv chine is a shaft 4) having fast upon itsforward end a group of cams preferably formed as a unit hereinafter designated as a cam member and indicated generally by the numeral 52. Fast upon a sleeve 54 rotatably mounted upon the shaft 50 but secured against endwise movement is a clutch member 56 to which is rigidly secured a bevel gear 58 meshing with the bevel gear 34. fllidably and rotatably mounted upon the shaft 50 is a. clutch member 60 having a clutch face 62 arranged to be moved into and out of engagement with the adjacent surface of the clutch member 56 and a brake surface 64 .i correspondingly moved out of and into eni spring 74 surrounding projections 68 and 70 and bearing at its forward end against a plane surface formed upon the rear of the cam member 52, the spring 74 thus tending to move the clutch member rearwardly into power transmitting position.

Threaded upon and rigidly clamped to the clutch member 60 is a collar 'l' 6 to the rear of which is a hub 'Z8 mounted for endwis-e movement relatively to the clutch member 60 f. and provided with pair of pins on opposite sides of the shaft 50 and engaging hooks formed at the upper end of a lever 82 fulcrumed at 84 to the head of the machine. Thus when the lever 82 is held in the position shown in Fig. 4 the spring 74 is compressed and the clutch member 60 is maintained in its forward or non-power transmitting position while when the lever is rocked by mechanism hereinafter' described in a counter-cioe wise direction from the position of Fig. 4 to the position of Fig. 5 the clutch member 60 is mov d rearwardly by the force of the spring 74 into engagement with the continually driven clutch member 56 and to transmit power to the cam member 52.

The illustrated machine is provided with a single tool (Figs. 4, 7 and 8) arranged to operate both as an owl and as a driver. This tool 100 is clamped at 102 to a tool carrier 104 mounted for vertical reciprocation in a guideway 106 carried by or formed in the head 36 of the machine.

The mechanism for giving the tool 100 its awl stroke and its driver stroke includes a lever 112 fulcrumed at 110 (Figs. 1, 4, and 10) to the head of the machine and having two parallel arms pivoted at their rear ends to a link 114 (Figs. 1 and 9) positioned approximately vertically and having a pivoted bearing at its low-er end in a slot 116 formed in a rearwardly extending arm of a bell crank lever 118 fulorumed at 120 to the head of the machine and having an upwardly extending arm 122 carrying a cam roll 124 positioned in a cam track 126 formed in cam member 52. Slot 116 is formed on an arc of a circle having a raoius equal to the distance between the pivots of link 114 and positioned concentric with the pivotal connection between link 114 and lever 112 at the time of the driver stroke oftool 100. As means hereinafter described is provided for preventing undesired movement of the link 114 lengthwise of the slot 116, it will be seen that the rocking movement imparted to the bell crank lever 118 by the cam track 126 operates cyclically to rock the lever 112 up and down about its fulcrum 110. The form of the cam slot 126 is such as to position the lever 112 in its uppermost position early in the cycle of operation when the tool 100 is acting as an awl and to position the lever 112 in its lowermost position later in the cycle when the tool is operating as a driver.

Fulcrumed at 130 to the lever 112 is another lever 132 (Figs. 4 and 10) formed at its forward end with teeth 134 entering the openings between corresponding teeth 136 formed in the upper end of the tool carrier 104. A stiff coil spring 138 surrounds the fulcrum 130 of the lever 132 and is anchored at one end to a disk 140 adjustably secured to the lever-112, as by a pin 142. Atits other end the spring 138 is secured to a housing 144v secured to or formed as part of the lever 132. As illustrated in Fig. 4 the end of the spring 138 is anchored by projecting through a lhole formed in the housing 144. Thus th-e spring-138 tends at all times to rock the lever 132 in a clockwise direction as viewed in Fig. 4 and to urge the tool carrier 104 and the tool 100v downwardly.

At its forward end the cam member 52 is provided with a lifting cam (Figs. 4 and 9) having a pair of elevated portions 152, 154. Mounted for vertical sliding movement in the head 36 of the machine is a lifting bar 156 .the lower end of which bears against the cam 150 and thus serves as a lifting block. Pivoted to the lifting bar 156 is a block 158 positioned in a slot formed in the lever 132. Thus as the cam member 52 rotates, the lifting bar 156 is elevated by the cam 150, the lever 132 being rocked upwardly and the spring 138 correspondingly compressed. Then when the elevated portion 152 or the elevated portion 154 of the cam 150 passes out from beneath the lower end of the lifting bar 156, the spring 138 forces the lifting bar 156 and the lifting block 158 downwardly thusl rocking the forward end of the lever 132 downwardly in a clockwise direction as shown in Fig. 4, and forcing the tool carrier 104 and the tool 100 also downwardly, A

CTI

bumper 157 clamped to the upper end of theV lifting bar 156 impinges upon a boss 159, thus limiting the downward stroke of the lifting bar 156. In the illustrated machine the elevated portion 152 of cam 150 passes out from beneath the lifting bar 156 when the fulcrum 130 of the lever 132 is in its uppermost position, the tool then being forced downwardly 'through a nozzle 162 and into the work to form a fastening receiving hole. Vhen the shaft 50 has been rotated through another 180, and the elevated portion 154 of the cam 15() has raised the lifting bar 156 and passed out from beneath the lifting bar,

, the fulcrum of the lever 132 has been moved to its lowermost position. rl"hus the downward movement of the tool carrier 104 and the tool 100 is only suilicient to drive the fastening which at that time has been brought into alinement udth the throat opening of a nozzle 162 and with the tool 100. In order that the two strokes of the tool 100, though terminating at different points, may be approximately of the same length, the elevated portion 154 of the cam 150 is as shown in Fig. 9, somewhat higher than the elevated portion 152.

ln order to permitthe machine to be used to drive fastenings of either one of two lengths may be desired, for example, in lilclay sole laying where it is preferablel to use shorter fastenings to attach the forepart of the sole than are used in the heel-seat, the machine is provided with additional mechai ism which will now be described for varying the position of the lever 112 and the fulcrum 130 of the lever 132 at the time of the awl stroke of the tool 100. For this purpose link 114 is pivotally connected somewhat above its lower end to a link pivoted at its other ond to an approximately vertical lover 172 fu crumed at 120 to the hea-d of the machine and having its lower end connected bv a link 17l to a bell crank lever 176 fulcrumed at 178 to the head of the machine (F` 1, 8 and 9) and urged in a counterclo\ 'isc direction as shown in Fig. 1 by a .feg to; 179 (Fig. 8). The bell crank lever 176 has a rearwardlyextending arm connecj l by an adjustable rod 180 to a controller or i eadle 184 mounted in the base of the machine and arranged by its displacement to more the rod 180 downwardly thus rocking the bell crank lever 176 and the lever 172 in a clockwise direction, as viewed in Fig. 1, against the action of spring 179 and moving the lower end of the link 114 rearwardly in the '.-ot 116 of lever 118. Thus when the oporatoi steps upon the treadle 184 the amplitude of the rocking movement of the lever 112 about fulcruni 110 is greater than when the t eadle 184 is in its normal position. The fulcrum 130 of the lever 132 is, accordingly, raised to a wearer extent at the time of the awl stroke of the tool 100` if the treadle 184 is displaced, and the forward end of the lever 132 is correspondingly lowered to a greater extent at the time of the awl stroke of tool 160 so that a deeper hole is made in the Work piece presented to the nozzle 162.

ln order definitely to determine the depths of the holes formed in the work according as the treadle 184 is elevated or depressed, the bell crank lever 176 is provided with a slot (Figs. 1 and 3) in which is carried a pair of adjustable stops 192, 194 clamped in the desired position Vby screws 196, 198. A stationary pin 200 carried by the head 36 of the machine is engaged by one or the other of the stops 192, 194, and thus controls the upper position of the treadle 184 and the extent to which the treadle can be displaced. Conveniently a scale 202 is carried by the lever 176 to aid in the proper positioning of the stops 192, 194.

The illustrated machine is arranged to be started by upward displacement of the nozzle 162 accomplished by pressure of the work against the nozzle. For this purpose the nozzle 162, which is mounted for vertical sliding movement, carries a pin 210 (Figs. 4 and 8) positioned in slot formed in the forwardly extending arm of a bell crank lever 212 fulcrumed at 214 to the hea-d of the machine. An upwardly extending arm of the bell crank lever 212 is connected by an adjustable link 216 to the upwardly extending arm 218 of a second bell crank lever 220 (Figs. 4 and 5) fulcrumed on a short stationary shaft 222 to the head 36 of the machine. A rearwardly and downwardly extending arm 224 of the bell crank lever 220 is provided with a bearing for a short shaft 226 to which are pinned an upwardly extending linger 228 and a hook 230 positioned when the machine is at rest above a. lug 232 (see particularly Fig. 6) projecting from a latch member 234 pivoted to the head of the machine at 222 and thus movable about the fulcrum of the bell crank lever 220. A spring 236 anchored at one end to the latch member 234 and at the other end to a stationary part of the machine tends to rock the latch member 234 in a clockwise direction as viewed in Figs. 4, 5, and 6. Toward its rear end the latch member 234 is provided with a notch 238 (Fig. 5) ,forwardly of which is an arcuate surface 240 best shown in Fig. 6. Pivoted at 250 to the lever 82 is a bell crank lever 252 having a forwardly extending arm 254 and a depending arm 255 (Fig. 5) arranged when the machine is at rest to be positioned in the notch 238 of the latch member 234. Pivoted to the forward extremity of the forwardly extending arm 254 of the bell crank lever 252 is a link 256, the bell crank lever 252 and the link 256 thus forming a toggle. The forward extremity of the link 256 is pivoted to a rod 258 (Fig. 4) mounted for sliding movement in bearings formed in the head 36 of the machine and carrying a roll 260 engaging a cam track 262 formed in the cam member' 52. A spring 270 connected at one end to the fulcrum 250 and at the other end to the linger 228 tends to maintain the finger 228 in an approximately vertical position with its upper end bearing against an extension of the fulcrum 250, and tends at the same time to lift the rearwardly extending arm of the bell crank lever 220 and thus to maintain the link 216 in its forward position, and the nozzle l62 lowered. The spring 270 also tends to hold the hook 230 in position to engage the lug of the latch member 234.

The machine comes to rest with the parts which have just been described in the position shown in Fig. 4. ln this position it should be observed that the toggle formed by the bell crank lever 252 and the link` 256 is partly broken, and is held latched in this condition by the engagement of the lower end of t-he depending arm 255 of the bell crank lever 252 with the notch 238 of the latch 234. This holds the lever 82 securely in the position shown in Fig. 4 with the spring 7 4 under compression and the clutch member in non-power transmitting position. Vfhen the nozzle 162 is displaced upwardly by the pressure of a work piece presented thereto, the bell crank lever 220 is rocked, through bell cranklever 212 and link 216, in a counterclockwise direction as viewed in Figs. 4 and 5, thus moving the hook 230 downwardly and rocking the latch member 234 in a counterclockwise direction against the action of spring 236 to an extent suflicient to release the lower end of the arm 255 of the bell crank lever 252 from the notch 238l of the latch member 234, the lower end of the arm 255 of the bell crank lever'252 moving to the right and upwardly along the arcuate surface 240 as the toggle formed by the bell crank lever 252 and the link 256 breaks completely under the pressure applied to the upper end of the lever 82 by the spring 7 4. Thus the clutch member 60 is moved rearwardly by the spring 7 4 to power-transmitting position and the machine starts. In order to stop the machine at the end of each cycle of operation, engagement of the extension of the pivot 250 with the finger 228 early in each cycle of operation rocks the finger 228 to the right, as viewed in Figs. 4 and 5, moving the hook 230 away from the lug 232 so that the latch member 234 is held depressed merely by the lower end of the depending arm 255 of the bell crank lever 252, these parts thus serving as a throwout device to limit the operation of the machine to a single cycle. As the cam member 52 rotates, the cam roll 260 is moved forwardly carrying the rod 258 with it and straightening the toggle 252, 256, so that when later in the cycle the rod 258 is moved rearwardly by the cam 262, the lower end of the lever 82 is moved to the left to approximately the position shown in Fig. 4. Art the same time the lower end of the varm 255 of lever 254 enters the notch 238 of latch member 234, which is moved upwardly by spring 236. Further movement of the rod 258 rearwardly by the action of the roll 260 and the cam 262, while the lower end of the depending arm 255 of the bell crank lever 252 is held by the latch member 234, results in rocking bell crank lever 252 somewhat (in a counterclockwise direction as viewed in Fig. 4) and thereby partly breaks the toggle, as shown in Fig. 4, as the machine comes to rest. This leaves the machine in such a condition that the force applied by the spring T4 is sufficient to complete the breaking of the toggle as soon as the latch 234 is tripped and the tripping of the latch234 requires no greater pressure than can easily be exerted by the operator against the nozzle 162, no greater pressure, indeed, than is desirable to insure that the outsole is pressed suiiiciently firmly against the lasted shoe upper and insole. With such a construction it is not necessary for the operator manually to exert the comparatively heavy pressure necessary to overcome the friction between the toggle members and pins which is comparatively large during the early part of the breaking of the toggle when the toggle members are in a straight line or substantially so. Y lt should be noted also that by varying the extent to which the breaking movement of the toggle 252, 256 is carried before it is latched and the machine comes to rest, the force necessary to trip the latch 234 may be varied within considerable limits. In the illustrated machine such adjustment may be made by varying the position of the collar 7 6 which as before stated, is shown as threaded upon as well as clamped to the forwardly extending portion of the clutchmember 60 or by adjusting an eccentric bushing 257 which forms the bearing of the latch member 234 on its shaft 222. y

The paper twine 300 from which the libre pegs inserted by the illustrated machine are cut is carried by a reel 302 (Fig. 4) rotatably mounted upon the head 36 of the machine. From the reel 302 the twine 300 passes through a tubular guide member 304 mounted for vertical reciprocating movement at the front of the head of the machine (Figs. 2, 4, and 8). Fulcrumed at 306 (Fig. 2) to a projectingv portion 308 formed upon the lower end of the guide 304 is a small bell crank lever 3l@ having an arm projecting approximately horizontally and parallel to a link 312 also pivoted at 306 to the guide 304. A dog 314 (bestI shown in Fig. 2) having a flat face 316 arranged for engagement with the strip of fastening material 300 is pivoted at 31.8 to the link and the bell` crank lever 310. A spring 320 anchored at one end to the link 312 and the bell crank lever 310 and at the other end to the projecting portion 308 of the guide 304 tends to rock the bell crank lever 310 and the link 312 in a clockwise direction, as viewed in Fig. 2, so that, as the guide member 304 is moved downwardly by mechanism hereinafter described, the dog 314 will grip the strip of fastening material 300, pressing the strip firmly against the lower portion of the guide member 304, that part of which is cut away (as shown in Fig. 2) to a semi-cylindrical form, and feeding the fastening material downwardly. Upward movement of the guide member 304 tends to rock the bell crank lever 310 and the link 312 in a counterclockwise direction, as viewed in Fig. 2, releasing the hold of the dog 314 against the strip of fastening material 300 so that the dog 314 can move upwardly to get a new grip upon the strip 300. To prevent retrograde movement of the strip of material 300 if the strip should stick to dog 314 during the upward movement of guide member 304, a second dog 322 is provided. This dog 322 is carried at the left end, as shown in Fig. 2 of a pair of links 324 fulcrumed at 326 to the head 36 of the machine and urged upwardly in a clockwise direction by a spring 328 anchored at one end to the links 324 and at the other end to the head 36. The dog 322 is so mounted as freely to permit downward or feeding movement of the strip of material 300 but holds that strip firmly against retrograde movement. The dog 322 lJo-operates with an upwardly projecting semi-cylindrical portion 330 of a stationary guide member 332 from which a tube 334 conducts the strip of fastening material 300 to an opening 336 (Fig. 7) formed in a shear member 338 secured at the forward end of a rod 340 mounted for endwise sliding movement in a guide formed in the head of the machine, and clamped, as shown at 342 in Fig. 9, to the rod 258. Cooperating with the shear member 338 is a second shear niember 344 at the lower extremity of the tube 334. Thus it will be seen that early in each cycle of operation as the rod 258 is moved forwardly by the cam 262 a fibre peg will be severed from vthe strip of fastening material 300 and carried forwardinto the line of drive. As illustrated in Fig. 7 the portion of the head 36 between the nozzle 162 and the shear member 338 is provided with an opening or passageway 346 through which the fastening passes from the opening 336 in the shear member 338 to the throat opening of the nozzle 162. A

The vertically movable guide member 304 is reciprocated through a path variable in accordance with the lengths of the fastenings to be inserted by a mechanism which will now be described. Pivoted at 350 to the guide member 304 is a link 352 (Figs. 1 and 2) the other end of which is pivoted at 354 to the forward end 0f a bell crank lever 356 fulcrumed at 358 to the head 36 of the machine and having a depending arm 360 pivoted to an approximately horizontal link 362 the rear end of which is pivoted to the depending arm of a bell crank lever 364 fulcrumed on thephead 36. A forwardly extending arm 366 (Figs. 1 and 4) of the bell crank lever 364 is provided with a slot 368 in'which is located a slide block 369 adjustablyy clamped in place by a hand screw 371 shown in Fig. 8 but broken away in Fig. 1 to show the slide block 369. A link 372 is pivot'ed at its lower end to the slide block 369 and at its upper end to the rear end of the lever 112. Thus it will be seen that the rocking of the lever 112 about` its fulcrum 110 is operative to reciprocate the guide member 304 and the strip-engaging dog 314 carried at its lower end, and the extent of this reciprocating movement is dependent upon the extent of the rocking movement of the lever 112 so that the depression of the treadie 184 is effective not only to cause the formati-on of a deeper hole in the work by the awl stroke of the tool 100, but also to cause the feeding and severing of a correu spondingly longer peg for insertion in the deeper hole. Adjust-ment of the slide block 369 in slot 368 of the lever 364 varies the relation of the length of the fastenings to the depths of the holes formed in the workpiece, for example to permit desired variations in the heading of the fastenings on the surface of the work.

Depression of the treadle 184 when the machine is at rest operates to rock the lever 112 somewhat. Thus the repeated depression of the treadle 184 might result inthe feeding forward of the strip 300 of fastening inserting material t0 such an extent as to cause the strip of material to jam Vin the machine. Accordingly, the machine is provided with mechanism for releasing the lengagement of the feed dog 314 upon the strip 300 of fastening material as the machine comes to rest,

the dog 314 not being permitted to return e i to engagement with the strip 300 vuntil the machine has actually been started again. For this purpose the depending arm of the bell crank lever 310 is formed with a surface 400 arranged for engagement with a surface 402 formed upon a lever 404 fulcrumed at 406 to the head of the machine (see particularly Fig. 2) and having its lower end bent to the left as viewed in Fig. 2, and provided with a vertical slot 408 engaging a crank pin 410 carried 'bythe forward extremity of the shaft- 50. The crank pin 410 is so located relatively to the aXis of the shaft that the 1nachine comes to rest with the crank pin 410 in the position shown in Fig. 2 in which it will be seen that the surface 402 cf the lever 404 has engaged the surface 400 of the bell crank lever 310, and has rocked the latter in a counter-clockwiee direction sufficiently' to release the dog 314; from the strip of fastening material 300.

lVhile the operation of the various parts of the machine has already been tescribed, it may be helpful to consider non the opera tion of the machine as a whole. lilith the parts of the machine in the position shown in Fig. 4, the work in which fastenings are to be inserted (for example a lasted McKay shoe to which the outsole is to be preliminarily attached or laid) is presented by the operator to the nozzle 162, the nozzle being forced upwardly by pressure applied through the work. The displacement of the nozzle 162 trips the latch 234, rocking that latch in a counter-clockwise direction to the position shown in Fig. and permitting` the breaking of t-he toggle 252, 256 under the influence of the spring The spring 7e thus moves the clutch member 60 to the left, as shown in Fig. ehiinto power transmitting position and the cam member 52 begins to rotate. During the early part of the cycle the lever 112 is moved to its uppermost position so that the first stroke of the tool is an awl stroke, the tool 100 being` driven down and passing out beyond the lower end of the nozzle 162 to form a hole in the work. At the'same time the guide member 304 is moved upwardly, the dog 322, however, engaging the strip 300 and preventing retrograde movement thereof. rllhen the lifting bar 159 and the tool 100 are lifted by the elevated portion 154e of the lifting cam 150, the lever 112 being rocked at the same time about -its fulcrnm to lower the fulcrum of the lever 132 so that the nextstroke of the tool 100 will serve as a driving stroke. At the same time the guide member 30st is moved downwardly causing the dog 31e to feed the strip of fastening material 300 an appropriate distance. yl`he shear member 338 then moves forwardly to sever a fastening and to bring the opening 336 into alinement with the tool 100 and the openingin the nozzle 162. After this, as the elevated portion 15e of the cam 150 passes out from beneath the lifting bar 156, the spring 188 again forces the lifting bar 156 and the lever 132 downwardly to cause the driver stroke of the tool 100. As the shear member 33S moves forwardly, the toggle 252, 256 is straightened so that as the rod 258 moves rearwardly after the fastening has been driven, the lever 82 will be rocked about its fulcrum 84 compressing` the spring 74; and moving the clutch member 60 into nondriving position. 1s the lever 82 is thus rocked, the lower end of the bell crank lever 252 is caught in the notch 23S of the latch member 23% and the continued movement of the rod 258 together with a slight additional roch' of the lever 82 are eliective to start the breaking 0l? the toggle 252, 256 so that the machine comes to rest with the toggle latched in a partly broken condition as shown in Fig. 11.
